Thank you for your response. There is no single font that contains all languages that we need, does Godot able to perform fallback by order to next font when the required glyph is not found is first supplied font?
Yes, you can specify one or several font fallbacks with DynamicFont. By the way, you may be interested in Noto Fonts, which can cover a very wide selection of languages. We use Droid Sans in the editor (and Source Code Pro for script editor) because Noto Sans can get really large with lots of languages (dozens of megabytes, if I remember).
